imageWhen talking about sun safety, we talk primarily about the skin, however, protecting your eyes from the damaging rays of the sun is just as important as applying sunscreen.

Lens colors affect how much visible light reaches your eyes, so it is important to know which colour lenses would be right for you.

Make sure your lenses are dark enough to keep your eyes comfortable, and that you wear your sunglasses every time you go outside.  Just like wearing sun screen, wearing sunglasses needs be part of your lifestyle.

Dark Colour Lenses: Brown, Gray & Green

These colour lenses are great for everyday use and outdoor activities. Darker shades are intended to cut through the glare and reduce eyestrain in moderate-to-bright conditions.  Darker colour lenses limit colour distortion.

Dark colour lenses are great for general daily use, and provide true colour perception, and aid in preventing eye fatigue during outdoor activities, where glare is not an issue.

Light Colour Lenses: Gold, Yellow, Amber, Red & Rose:

These colors excel in moderate to low light conditions.  They provide excellent depth perception, enhance contrasts, improve the visibility of objects and make your surroundings appear brighter.

Light colour lenses  are great enhancers for vision by giving you high contrast, enhanced depth perception, and reduced glare. They are helpful for any sport where distance needs to be judged such as golf or racquet sports.

Here is a quick colour break down to help decided what colour lenses are best for you:

The basic rule of thumb for choosing a lens is to consider color opposites. Blue is opposite of Yellow and Red is opposite of Green. Red lenses will absorb Green light and Yellow Lenses will absorb Blue/Ultraviolet light, and vice versa.

Green – green lenses work the same in any light conditions, so can be used for any outdoor activity.  Green tints reduce glare, while offering high contrast and visual sharpness.

  • Good for general purpose use
  • Offers even color perception
  • Dims glare while brightening shadows
  • Provides good contrast for low-light conditions

Gray – Gray is a popular neutral tint that allows the eyes to perceive colors in its purest form. Gray tints reduce brightness and glare. Choose gray for driving and outdoor sports.

  • Good for general purpose use
  • Reduces eye fatigue
  • Provides true color perception
  • Minimizes glare, especially off water

Brown / Amber – These lenses are great for activities like tennis, golf or other sports where distance is a factor and must be calculated.  Brown tints reduce glare and block blue light, giving them the ability to brighten vision on cloudy days.

  • Good for variable conditions
  • Enhances contrast
  • Improve depth perception

Yellow/Orange – Yellow and orange tints increase contrast in low-light conditions. These tints tend to make objects appear sharper both indoors and outdoors.

• Filters out hazy light that is hard on the eyes
• Good for using at Dawn and Dusk
•Provides greater clarity in fog, haze, and other low-light conditions

Pink and Red – These colours provide better visibility on the road, by improving visual depth & reducing eye strain.

  • Provides good road visibility
  • Offers greatest amount of contrast

Blue and Purple –   These colours block the glare from visible white light. Useful for outdoor sports,  such as snowboarding, biking, or sailing.

  • Helps define contours
  • Reduces glare
  • Enhances color perception

What ever colour choice you pick, remember the most important thing is to wear your sunglasses!

imagesPart of body maintenance is having a yearly physical, visiting the dentist once or twice a year,  as well as seeing a healthcare practitioner (physiotherapist, massage therapist, chiropractor, acupuncturist) however, most of us forget to book a yearly appointment with an optometrist about our eye health.

Part of good eye health is being preventative….. here are some guidelines to help you get started.

Wear Protective Glasses

Protective eye wear are safety glasses that are designed to provide protection from activities that could be a risk to your eyes, such as playing sports, operating equipment at work, or using chemical at home .

No Smoking

Research has linked smoking to an increased risk of developing age-related macular degeneration, and cataracts; all of which can lead to blindness.

Wear Sunglasses

Sunglasses protect your eyes from the sun’s ultraviolet rays. Purchase sunglasses that block out 99 to 100 percent of both UVA and UVB radiation.

Exercise Your Eyes

When you spend large amounts of time working on computers, tablets, e-readers, and other devices with visual displays your eyes can get fatigued, and you can suffer from digital eye strain and computer vision syndrome. Try the 20-20-20 rule, which will help reduce eyestrain: Every 20 minutes, look away about 20 feet in front of you for 20 seconds. Looking far away relaxes the focusing muscle inside the eye to reduce fatigue.

Adjust the Lighting

Eye strain can be caused by bright light, either coming in through window (sunlight) or from interior lighting. Eliminate bright light and minimize glare, by closing the blinds or by turning off some of the overhead lights; and position your computer monitor so that it’s not directly in front or behind a window.

Invest in a LCD Screen

LCD screens are easier on the eyes and usually have an anti-reflective surface.  Also try to work at a display screen that has a diagonal screen size of at least 19 inches.

 Adjust the Display Settings on your Device.

Get in the habit of adjusting the brightness, text size, colour and contrast of the display screen you are working on. Be aware of your surrounding and adjust accordingly.

Take Frequent Breaks

To reduce your risk for computer vision syndrome and neck, back and shoulder pain, take frequent breaks throughout your work day.  For every hour of sitting, take a 10 minute break where you move around and stretch to reduce tension and muscle fatigue.

Modify Your Workstation

Adjust your workstation and chair to the correct height. You are at the correct height when your head and neck are upright and in-line with your torso. Position your computer display so the top of the screen is slightly below eye level; this will allow you to view the screen without bending your neck.

Like all body maintenance, taking care of your eyes will help ensure that you will enjoying a lifetime of healthy vision.
